LUBRICANT-ATOMIZER.

Specification 01 Letters Patent. Patented Sept]. 14, 1915,

Application filed January 16, 1913. Serial No. 742,388.

To all whom it may] concern Be it known that I, GEORGE PRIsKEY, a citizen of the United States of America, re siding at Detroit, in the county of "Wayne and State of Michigan, have invented certain new and useful Improvements in Lu bricant-Atomizers, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to lubricant atoInizers and more particularly to that type of atomizer adapted to be arranged in a steampipe of an engine in advance of the cylinder.

The invention has among the objects thereof to provide a nozzle whereby the o l may be thoroughly atomized and carried 1n suspension in the steam to the parts to be lubr1- oated; to provide a device which while efficiently atomizing the oil, will prevent the oil from being deflected against thewalls of the steam-pipe as it leaves the atomizer, and to permit the atomizer to be readily apphed to the steam-pipe without dissembling the latter or without employing special fittings.

Other objects of the invention will more fully hereinafter appear.

The invention resides inthe peculiar construction, arrangement and combination of parts as will be herein describedand more particularly pointed out in the claims.

In the drawings,Figure 1 is a d1agrammatic representation showing the relation of the atomizer to the lubricator and steampipe; Fig. 2 is a perspective View of my 1mproved atomizer; Fig. 3 is a longitudinal, central section therethrough; Fig. 4 isa section on the linear-50 of Fig. 3; and Fig. 5 illustrates a modification.

A designates the steam-pipe of a steam engine, the steam passing therethrough 1n the direction of the arrow, and B designates the lubricator, attached to the pipe A in the usual manner.

D is my improved atomizer which is connected to the outlet E of the lubricator and has its discharge end positioned within the pipe A, preferably centrally thereof. As

shown, the atomizer has a body portion F screw-threaded at one end to engage a bushing G which is attached to the lubrioator outlet, and this body portion termmates in a nozzle portion H arranged at substantially right angles thereof. At the top of the nozzle is a projection I having an opening J in alinement with, but of smaller size than the bore K of the nozzle. The wall around the opening J is preferably beveled as indicated at I so as to direct the steam thereinto.

In operation the steam will enter the opening I, passing through the bore K and discharge out through the openings L in the end of the nozzle. Therefore, the lubricant as it passes into the bore J from the body portion of the atomizer will commingle with the steam and be considerably broken up and atomized thereby, since the velocity of the steam passing through the nozzle is very high. As the commingled steam and lubricant leaves the nozzle it is further atomized, but the shape of the discharge end is such as to cause the steam and lubricant leaving the nozzle to be sprayed downward and not to be deflected sidewise upon the walls of the steam-pipe. Thus the discharge end is formed by a plurality of spaced prongs K, preferably made by cutting away the metal at the end of the nozzle, bent inward until their free ends meet. The sides of the prongs are beveled as indicated at M so as to abut and form a close point or end N for the nozzle. This provides longitudinally, tapering discharge openings L which also diverge inward so that the distance between diametrically opposite openings is less than the diameter of the bore K. Therefore, the steam in immediate proximity to the walls of the bore K can pass vertically downward out through the openings L without impinging against the closed end N. This, together with the steam passing through the pipe A exteriorly of the nozzle, not only produces the effect of an ejector, but also preventsto a material extent the discharge from the nozzle from being sprayed upon the sides of the steam-pipe A. Further, since the aperture or opening J is smaller in size than the bore K, steam cannot rebound so to speak, out through the top of the nozzle after it has once entered the same. It will be noted upon reference to Fig. 3 that the steam entering the nozzle passes across the end of the bore 0 of the body portion and, therefore, will tend to siphon or draw the oil out of the bore 0.

In the modification shown in Fig. 5 the opening at the top of the nozzle is extended downward within the bore of the latter, as by arranging in the bore J as an extension of the opening, a conduit or pipe P which may be either cast as an integral part of the nozzle or formed as a separate member suitably secured thereto. This latter arrangement will materially increase the siphoning of the oil from the passage 0 and is exceedingly desirable in case a thick or heavy oil is used.

In both constructions it Wlll be noted that the atomizer may be inserted through an opening in the side of the steam-pipe, since pipe to receive the nozzle.

What I claim as myinvention is 1. The combination with a steam pipe, of a lubricant atomizer therein, the atomizer including a nozzle having a discharge end tapering toward its outer extremity, a yer tically extending bore, and an opening at the top of the nozzle of smaller size than the bore of the nozzle communicating therewith and with the interior of the steam'pipe.

2. In an atomizer, a nozzle having a bore extending therethrough and an opening leading to the top of the nozzle of smaller size than and communicating with the bore, said nozzle having a discharge end provided with a plurality of elongated tapering openings closed at their outer ends.

3. In an atomizer, a nozzle having a bore extending therethrough, and an opening of smaller size than and communicating with the bore leading eXteriorly of the nozzle oppositethe discharge end'of the latter, and a pipe of substantially the same cross sectional area as the said opening extending therefrom to the interior of the nozzle.

Gopies of this patent may be obtained for charge end formed by a plurality of spaced prongsextending inwardly with their free ends in engagement, the sides of the prongsbeing beveled and abutting to form a closed 7 point for the nozzle.

6. The combination with a fluid conduit, 7

ofalubricant atomizer therein, said atomk izer including a nozzle having a discharge end tapering toward its outer extremityand provided with a plurality of elongated side,.of a curved nozzle in which the two arms of the curved nozzle run substantially perpendicular to each other beyond the.

curve, the said curved portion of the nozzle being provided with a small ofitset having a passageway in alinement with the passages way through the arm at the free end of the nozzle, the said nozzle being provided at the '7 opposite end with a coupler memberof somewhat larger diameter and provided with external screwthreads for running upon the threads in the side of the steam pipe, the larger diameter of the coupler giving. a suificient opening through the side of the steam pipe to allow the insertion-of the nozzle carrying the oflset, whereby the nozzle may be screwed into the side of the steam pipe to bring the outer arm into the steam column and the offset. opening the line of the incoming steam.
